Online Volume Expansion • Performing a volume expansion on the controller is the process of growing only the size of the latest volume.

  • Page 159: Understanding Raid

    APPENDIX Appendix F Understanding RAID RAID is an acronym for Redundant Array of Independent Disks. It is an array of multiple independent hard disk drives that provides high performance and fault tolerance. The SAS RAID control- ler implements several levels of the Berkeley RAID technology. An appropriate RAID level is selected when the volume sets are defined or created.
  • Page 160 APPENDIX RAID 1 RAID 1 is also known as “disk mirroring”; data written on one disk drive is simultaneously written to another disk drive. Read performance will be enhanced if the array controller can, in paral- lel, access both members of a mirrored pair. During writes, there will be a minor performance penalty when compared to writing to a single disk.

  • Page 161: Raid 3

    A, B, C, D and E. In this configura- tion, each strip is mirrored on an adjacent disk with wrap-around. Areca RAID 10 offers a little more flexibility in choosing the num- ber of disks that can be used to constitute an array. The number can be even or odd.
  • Page 162 APPENDIX RAID 5 RAID 5 is sometimes called striping with parity at byte level. In RAID 5, the parity information is written to all of the drives in the controllers rather than being concentrated on a dedicated parity disk. If one drive in the system fails, the parity information can be used to reconstruct the data from that drive.

  • Page 163: Raid X0

    APPENDIX RAID 6 RAID 6 provides the highest reliability. It is similar to RAID 5, but it performs two different parity computations or the same compu- tation on overlapping subsets of the data. RAID 6 can offer fault tolerance greater than RAID 1 or RAID 5 but only consumes the capacity of 2 disk drives for distributed parity data.
